IMPROVEMENT IN GRAIN-DOORS.

Specification forming part of Letters Patent No. 213,491, dated March25, 1879 application filed January 27, 1879.

To all whom it may concern:

Be it known that I, GEORGE O. BANTA, of Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Grain-Doors and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form apart of thisspecification, and in which Figure 1 is a perspective view of myimproved door for grain or other.freight cars, grain-elevators, 850.Fig. 2 is a similar view of the same in a locked position. Fig. 3 isalso a similar View thereof with the door standing open, and Figs. 4 and5 are detail sectional views of the same.

Corresponding parts in the several figures are denoted by like letters.

This invention relates to certain improvements in doors for grain orother freight cars, grain-elevators, 860.; the object of which is toenable the easy and ready opening of the door, to effect the novellocking of the door, to permit of the door having a limited endwisemovement to allow it to swing outwardly, and to render the doorvertically adjustable, and adapted to be swung inwardly and sustained inan elevated position.

To these ends this invention consists, first, in the detailedconstruction of the fastening; secondly, in connecting one end of thedoor or gate to a rod by oblong or elongated eyes; and, thirdly, in soadjusting the door or gate in position as to effect the elevating andholdin g of the same up out of the way when opened, substantially ashereinafter more fully set forth.

In the accompanying drawings, A refers to the door-frame of agrain orfreight car or of a grain-elevator, as the case may be. B is a door orgate, such as is usually used upon the inside of the opening of the doorproper or outside door, to remove the pressure of the grain or otherlike merchandise from the said outside door, and to permit ofconvenience in reaching the grain in removing the latter.

One end of the door or gate B is provided with oblong or elongated eyesI) 1), preferably extended inwardly at about an acute angle to said endof door or gate, as clearly seen in Figs. 2 and 4, the object of whichis to cause them to enter mortises or recesses b I), Fig. 4, made in thejamb, and a strip, b fastened thereto, when the door or gate is closed,to assist in holding the latter down in place. These eyes receive a rod,O, fastened to or in the floor and ceiling, or upper part of the'[car orelevator, as the case may be, for the purpose of hanging the door orgate in position, and for enabling the same to be elevated and. swungaroundagainst the inside of the car or elevator, and rested upon thestrip 11 out of the way, while the car or elevator is being unloaded.The primary object of these eyes is to enable the gate or door to have alimited endwise movement, for the purpose of freeing it from the cleat cin opening the door, and to permit of the opening of the door outwardly.

D is the fastening, or an upright bar pivoted or hung to one side of theframe A at the forward end of the door or gate B, as seen in Figs. 1 and3. A pin or projection, d, projecting from the frame A and directly incontact with the upper end of the fastening D, holds the latter upon itspivots as against upward pressure. This fastening is beveled upon itsfront surface or edge, and is so hung in place that when said edge isswung around toward the door the latter will rest against said edge, andstand flush with the strip or bar 0 upon the inside of the car orelevator and fastened to the frame A. The strip or bar 6, which meetsthe front edge of the door or gate B, is extended sufficiently beyondthe inside surface of the frame A to break joints with the face of thefastening D, and thus prevent the escape of grain or other article atthat point. The upper end of the fastening or bar D is provided with aright-angled projection or arm, f, the function of which is to hold thegate or door down from rising when pressed upon by the grain or contentsof the car or elevator, as isapparent from Figs. 1 and 2. To theprojection or arm f is hinged a hasp, 9, adapted, when the fastening isbrought against the door B, to be connected or pinned to a staple oreye, It, by the peculiarly-shaped pin 6, which staple or eye is fastenedto the inside of the doorframe, car, or elevator.

j is a button afiixed to the inside of the doorframe or car, and adaptedto swing down by gravity and secure the dooror gate from swinging oropening inwardly.

Having thus fully described my invention, Iclaim and desire to secure byLetters Patcut- 1. The fastening D, hung or pivoted to one side of thedoor-frame, and provided at its upper end with a projection or arm, f,having a hinged hasp, g, substantially as and for the purpose specified.

2. The combination, with the fastening D, hung to the door-frame, andhax'in g a rightangled projection, f, provided with a hinged hasp, g, ofthe staple or eye h and pin 1', substantially as and for the purpose setforth.

3. The combination of the door or gate B, frame A, button j, fasteningD, having rightangled projection f, provided with a hinged has ,g,staple or eye h, and pin i, substantial y as and for the purpose setforth.

4. The door or gate B, having the elongated eyes or loops b b, incombination with the rod 0 and door-frame, or its equivalent,substantially as and for the purpose described.

5. The door or gate B, having the elongated eyes I) b, in combinationwith the rod 0 and frame A, with one of its uprights and a stripfastened thereto, provided With mortises or recesses b b substantiallyas and for the purpose explained.

6. The door or gate B, frame A, elongated eyes b, rod (1, button j,fastening D, having the right-angled arm or projection f, provided withthe hinged hasp g, staple or eye h, and pin 1', in combination,substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

GEORGE O. BANTA.
